LUBRICATING DEVICE.

SPECIFICATION forming part of LettersPatent No. 517,748, dated April 3,1894.

Application fuea Appli 14, 1390.

To @ZZ whom it may concern.-

B'eit known that I, HENRY P. l-IUMPHREY,

a citizen of the United States, residing at Nashua, in the county ofHillsborough and l State of New Hampshire, have invented a certain newand useful Improvement in Mechanical Oilers orLubricating Devices forJournal- Boxes for Shatting, of which the following is a specification.

My invention relates tol mechanical oilers or lubricating devices lforjournal-boxes for shafting and consists in the devices and comblnationshereinafter described and claimed.

In the accompanying drawings, Figure lis a front elevation of ashaft-hanger and a central, vertical, longitudinal section of ajournalbox adapted to be used with my improved mechanical oilersupported in said'hanger; Fig. 2, a side elevation of such a hanger anda vertical, central, transverse section of saidl journal-box, the lowerpart of the hanger and the part of the same immediately above theJournal-box being also in section in the same plane; Fig. 3, an enlargedvertical longitudiz 5 nal section of said journal-box showing thereservoir which receives the mechanical oiler and the 'oil-holesthroughA which oil is introduced by said oilerI into said j ournal-boxFig.` 4, a plan of said journal-box and my improved lubricating devices,a piece of shatting and a cam thereon to operate said devices, a part ofthe upper half of the outer shell of said journal-box being broken away,to show the internal construction land the cover of the reservoir beingopen forpthe same purpose; Fig; 5, a vertical transverse section on theline 5 f5 in Fig. 4, showing the mechanical oiler in side elevation, apart offthe barrel or cylinder of the pump being broken out to show thepiston-rod and the spring, Fig. 6, an isometric perspective view of thelever which operates the pump, detached.

The hanger A is of the kusual construction andmay represent any hangeror floor-bracket adapted to hold a journal-berlina horizontal position.

The journal-box B is not herein claimed being described and claimed inUnited States Letters Patent, No. 499,429, granted June 13, 50 1893,upon a division of .this application, but

Serial No. 347,760. (No model.)

consists of an inner shell or journal-box, proper B', formed in halves bb and lined with any anti-friction material, said halves lapping pasteach other, as shown at b2, to prevent a lateral movement ot' one halfupon the other. 55 The outer shell B2 is also formed in halves,one

of which laps past the other at b2, saidshell B2 lsurrounding the box Band the. ends of said shell extending beyond the ends of said box. Theouter shell B2 has annular ribs b4 on its in- 6o ner surface betweenwhich are arranged external annular ribs b5 on the journal-box B toprevent a longitudinal movement of the j ournal-box proper in said outershell, said ribs b5 on the box having lateral extensions tv-which 6 5 tnotches in the ribs b4 to prevent the journalbox proper turning in theshell. A projection 197 on the lower half of the shell enters a notch inthe upper halt` ofthe same and prevents said halves from moving endwiseon 7o each other. The shell has ears b8 whichrest yupon the fork a oftheV hanger in the usual manner, being held thereon by the set-screw dand check-nut, the point a4 of thescrew 'entering a depression b9 in acap b1@ which v7 5 rests on said shell, as described in said otherapplication. The lower half of the shell B2 is provided with a reservoircast or formed in one piece therewith and extending downwardly andlaterally therefrom to receive a 8o pump D, as shown in Figs. 4and 5,the cylinder d of said pump being provided with annular flanges orenlargements d d2, at or near its ends, said flanges resting against therear wall of said reservoir, against which they are held by a hook d3,adapted to ,reach partly around said cylinder d, and a bolt d4,extending through said wall into the shank of said hook, the head d5 ofsaid bolt resting against the outside of said wall. This means of se- 9ocuring the. pump in the reservoir allows it to be adjusted in heightwithout opening the reservoir, as by loosening the bolt d4'in the hook,the pump may be raised byvraising its spout d6 and in a similar mannermay be low- 95 ered and held in any desired height by again turning upsaid bolt into said hook.

The pump or oiler is of the usual construction having a piston-rod d1provided at its 4lower end with a piston or bucket (not shown) IoO andwith a spout d, through which oil from the reservoir is lifted by thepump D which discharges through an oil-hole Z212 in the top of the shellB2. The oil-hole Z112 is arranged concentrically with and above anoil-hole in the box B', and is surrounded at the inner end thereof by anannular boss Z113 of less diameter than said last-named oil-hole, toinsure the dropping of any oil that may be on the sides of the oil-holein the shell into the oil-hole in said box. For the same reason, theboss Z313 is tapered at its lower end to a sharp edge, as shown in Fig.3. The upper end of the piston-rod d19 is provided with a link 017, toreceive one arm of a lever ds which turns upon a rod or wire d, which issupported horizontally in the wall of the reser` voir 111.1. The end ofthe lever d8 farthest from the piston-rod reaches under a cam E,supported upon the shaft F, in such a manner that each revolution ofsaid shaft depresses said last-named end of said lever and raises thepiston-rod, the piston-rod being thrown downward or restored to positionby a spring 12, (Fig. 5,) substantially as shown in United States patentto me, No. 309,953, dated December 30, 1884. The cam E may be secured tothe shaft F in any convenient manner, as by the means shown in UnitedStates patent to 1ne,No. 333,950, dated January 5, 1886, where the camis represented as being secured to theshaft by wires, wrapped aroundsaid cam and shaft within grooves in said cam, but is preferably held onthe shaft by its own elasticity, as shown and described in United Statespatent to me, No. 329,904, dated November 10, 1885. The lever d5 isprevented from lateral displacement out of the path of said cam by itsconnection with the piston-rod, as above described, and also by havingarms d10d11, arranged between the fulcrum-rod d1 and the cam E, saidarms being extended sufficiently to fill the space between the oppositeside-walls of the reservoir, as shown in Fig. 4. The reservoir Z711 iscovered by the upper half of the shell and by a cover Z914, hinged at615 and below said cover and the upper half of the shell are arrangedall the parts of the oiler and its operating mechanism, except that thespout d reaches up through a notch (E18 in the cover. The oiler and thejournal-box are thus protected from the entrance of dust and lint andthe combined apparatus is made in as compact a form as possible and withas few risks of injury from blows.

When the devices abovedescribed are in operation and the oil is liftedby the pump, said oil passes through the oil-hole in the shell and theoil-hole in the box B to the shaft to be lubricated thereby andaccumulates in a recess Z218, formed in the upper half of the box byleaving out the anti-friction lining b1 at this place, the surplus oilrunning out at the ends of said box into said shell, at one end directlyinto the reservoir, while the oil discharged from the box at the endthereof farthest from the reservoir, flows through the space betweensaid box and outer shell back to said reservoir, the ribs h4 b5 beingcut away at the bottom of the shell and box at Z716 b1", as best shownin Figs. 3 and 5, to allow the oil to pass them. It is obvious that theribs 111125 may be replaced by projections suitably arranged topreventthe movement of the box within the shell.

By the above-described improvement, the bearing is virtually running inan oil-bath, thus lubricating the bearing in the mostperfeet mannerknown, and the shaft E may be kept sufiiciently lubricated at all times,for months or years, without reiilling the reser- Voir.
